Description
Technical field
The utility model relates to a kind of teaching aid, relates to a kind of multi-functional board wiper particularly.
Background technology
Upper class hour with under chalk end throw in nowhere, often arbitrarily abandon, adverse effect caused to classroom health.Many teachers also can invest scatterbrained student with chalk end in addition, if teacher also so does, also affect the image that teacher is a model for others, but utilize chalk end not invest student and directive blackboard or wall can play warning function to scatterbrained student equally.
And blackboard eraser is absolutely necessary in teaching, makes full use of blackboard eraser and to can yet be regarded as a kind of good mode to deposit chalk end.Applicant, through preliminary search, not yet finds that there is technical scheme like this type of.
Summary of the invention
For this reason, the utility model provides a kind of multi-functional board wiper, for solving the problems of the technologies described above.
Disclosed in the utility model, technical scheme is:
A kind of multi-functional board wiper, comprise rectangular plate body 1 and wrench 2, it is characterized in that: described plate body 1 is with the cavity of hollow, outside the upper surface deviating from wrench 2 at body 1, a pair chute 4 be connected as a single entity with body 1 is set, set within it in chute 4 draw back plate 5 slided, the gun barrel 10 be connected as a single entity with body 1 is set in the upper surface of body 1, gun barrel 10 is offered and communicates and the through hole 3 be connected as a single entity and groove 13 with the external world, piston 11 is set in gun barrel 10, one end that piston 11 deviates from through hole 3 arranges spring 12, piston 11 is linked together by the connecting rod 15 through groove 13 with draw back plate 5, the tube wall of gun barrel 10 is also arranged the second through hole 16 communicated with cavity, draw back plate 5 away from one end of through hole 3 with the block 14 blocked by the end face of chute 4, the side, side of body 1 is offered the window 6 that cavity communicates with the external world, the lid 7 of window 6 can be covered in the side hinged of window 6 body 1.
Further, described draw back plate 5 arranges a length of tape away from the position of through hole 3 and has the boss 8 strengthening friction texture.
Further, the free end of described lid 7 is arranged the buckle 9 be connected as a single entity with lid 7, described buckle 9 is fastened on the edge of window 6.
Compared with prior art, the utility model structure is simple, can not only hold chalk end, can also use as attention device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the structural representation of the utility model section components.
Detailed description of the invention
Below, with specific embodiments and the drawings is described in detail the utility model.
See Fig. 1-3.A kind of multi-functional board wiper, comprise rectangular plate body 1 and wrench 2, described plate body 1 is with the cavity of hollow, outside the upper surface deviating from wrench 2 at body 1, a pair chute 4 be connected as a single entity with body 1 is set, set within it in chute 4 draw back plate 5 slided, the gun barrel 10 be connected as a single entity with body 1 is set in the upper surface of body 1, gun barrel 10 is offered and communicates and the through hole 3 be connected as a single entity and groove 13 with the external world, piston 11 is set in gun barrel 10, one end that piston 11 deviates from through hole 3 arranges spring 12, piston 11 is linked together by the connecting rod 15 through groove 13 with draw back plate 5, the tube wall of gun barrel 10 is also arranged the second through hole 16 communicated with cavity, draw back plate 5 away from one end of through hole 3 with the block 14 blocked by the end face of chute 4, the side, side of body 1 is offered the window 6 that cavity communicates with the external world, the lid 7 of window 6 can be covered in the side hinged of window 6 body 1.Described draw back plate 5 arranges a length of tape away from the position of through hole 3 and has the boss 8 strengthening friction texture.The free end of described lid 7 is arranged the buckle 9 be connected as a single entity with lid 7, described buckle 9 is fastened on the edge of window 6.
When there is chalk end, by push-and-pull draw back plate 5, through hole 3 being exposed, being put in by chalk end, aim at the somewhere of wall, then unclamp draw back plate 5 immediately, chalk end launches away immediately, and student one is distracted, and spirit is braced up immediately, and draw back plate 5 covers through hole 3 simultaneously;
When not needing caution school, draw back plate 5 is slowly sent back to, and then tilt blackboard eraser an angle, and chalk end is just fallen in the cavity of blackboard eraser by the second through hole.
When being full of chalk end in cavity, open the lid 7, after chalk end being poured on dustbin, again close lid.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc.; all should be included within protection domain of the present utility model, it goes without doing projects chalk end to student for the utility model.
